30
Q

Carbon dioxide is a what?

A

Waste gas

31
Q

Equation for respiration?

A

Glucose + oxygen → carbon dioxide + water + energy

32
Q

To carry out respiration living things need to get what?

A

Oxygen from the air

33
Q

Living things need to get rid of what?

A

Carbon dioxide

34
Q

High carbon dioxide will what?

A

Poison cells

35
Q

Define gas exchange.

A

Process by which oxygen passes from air into body tissue and carbon dioxide leaves body tissue and enters air

36
Q

How do insects exchange gases?

A

Gases pass through tiny holes in their exoskeleton which lead to a branch of hollow tubes

37
Q

Why are alveoli surrounded by capillaries?

A

To uptake oxygen and transport oxygen in blood to cells in tissues

38
Q

Type of gas exchange in birds?

A

Lungs

39
Q

Type of gas exchange in sharks?

A

Gills

40
Q

Type of gas exchange in lady birds?

A

Spiracles

41
Q

Type of gas exchange in slugs?

A

Skin

42
Q

Type of gas exchange in oysters?

A

Gills

43
Q

Type of gas exchange in snakes?

A

Skin

44
Q

Type of gas exchange in spiders?

A

Spiracles

45
Q

Type of gas exchange in wombats and koalas?

A

Lungs

46
Q

Explain solubility in hot and cold water.

A

Oxygen dissolves better in cold water

47
Q

At what temperature do fish start to die of asphyxiation?

A

30 degrees

48
Q

Explain inhalation.

A

Air take in through trachea (windpipe) into lungs

Oxygen passes into bloodstream

49
Q

Define breathing.

A

Action of taking in and letting out air

50
Q

Diaphragm is drawn what when air rushes into lungs?

A

Downward

51
Q

Diaphragm does what as air is pushed out of lungs?

A

Relaxes into normal position

52
Q

Air travels where when breathing in?

A

Mouth → trachea → bronchi → bronchioles → alveoli → capillaries

53
Q

How do you test for carbon dioxide?

A

With the limewater test

54
Q

What colour will limewater turn if carbon dioxide is present?

A

White

55
Q

Label lungs.

A

Refer to year 9 biology national curriculum workbook (page 8)

56
Q

Which lung has only 2 lobes?

A

Left lobe

57
Q

Define bronchial tree?

A

The system of airways within the lungs which brings air from the trachea to lung’s alveoli

58
Q

Define cardiac notch.

A

Indentation in left lung that provides room for heart

59
Q

Define diaphragm.

A

Muscular membrane under lungs

60
Q

Define larynx.

A

Muscular structure at top of trachea containing vocal chords

61
Q

Define trachea.

A

Windpipe

Tube through which air travels from larynx to lungs

62
Q

Define vital capacity.

A

Vital capacity is the volume of air that your lungs can hold

63
Q

Describe what a lung looks like.

A

The lungs are a light pinky colour

64
Q

Describe what lungs feel like.

A

Light
Smooth and slippery
Easy to cut except the trachea which is much harder

65
Q

What is the formula equation for respiration?

A

C6H12O6 + O2 → CO2 + H2O + energy

66
Q
